BRAKE-BAND-LINER PUNCHING, COUNTERSINKING, AND RIVETING APPARATUS.

Application filed November 27, 1923. Serial No. 677,317.

To all whom it may concern:

Be it known that I, ANTHONY HAG-EN, a citizen of the United States, residing at San Die 0, in the county of San Diego and State of (Jalifornia, have invented a certain new and useful Brake-Band-Liner Punching, Countersinking, and Riveting Apparatus, of which the followin is a specification.

My invention re ates to a combined apparatus for punching and countersmking holes in liners for brake-bands and for riveting the liners to the same, and the objects of my invention are: First, to provide such an apparatus by which a rivet hole may be readily punched in the liner for a brakeband in alinement with the rivet hole in the band and by which the hole in the liner may be simultaneously countersunk to accommodate the head of a rivet; second, to provide an apparatus of this class by which a clean hole may be punched and countersunk in the liner and by which no severed or frayed ends of fabric are left exposed on the brake side of the liner; third, to provide an apparatus of this class by which a rivet, placed in the punched and countersunk hole of the liner and in the hole of the band, may be immediately and easily upset; fourth, to provide an apparatus of this class by which a rivet of common size may be upset 1n such a manner as to accommodate and fill difi'erent sizes of holes in the brake-band; fifth, to provide such an apparatus whereby the liner for one brake-band may be punched and countersunk while the liner of another brake-band may, at the same time, be riveted to its band; sixth, to provide a novelly arranged lever mechanism for simultaneously operating the punching and countersmkmg,

seventh, to provide as a whole a novelly conand the riveting devices of my apparatus; p

acters of reference thereon, which form a part of this application, in which:

Figure 1 is a plan view of my brake-band hner punching and rivet set apparatus, showing certain parts thereof broken away and showing fragmentary portions of brakebands positioned on and in connection with the same- Fig. 2 is a side elevational view thereof s owing certain parts and portions broken away and in section to facilitate the illustration and showing by dotted lines certain shifted positions of certain operating members; Fig. 3 is a fragmentary, sectional elevatlonal view of the hole punching and countersinking device of my apparatus, showing the punching and countersinking member piercing and forming the hole in the brake-band liner in alinement with the hole in the brake-band, and Fig. 4 is a fragmentary, sectional elevational view of the riveting device of my apparatus, showing the same forming a head on the one end of -the rivet extending through the brake-band and liner therefor.

Like'characters of reference refer to simithe pin 21, constitute the principal parts and portions of my apparatus.

The supporting frame 1 of my apparatus is preferably secured to a wall or on any convenient standard by means of bolts 2. Said frame is provided with two bifurcated ortions, the one at the lower inner portion thereof and the other positioned above and outwardly therefrom. At the outer end of the lower arm 1 of the upper, outwardly positioned, bifurcated portion of the frame is reciprocally mounted a pilot member 3, which is provided with a substantially conically shaped, outwardly extending end 3 and with an enlarged portion 3 at its inner end which retains said pilot member in'the supporting frame 1 and limits its outward movement, said enlarged portion 3 being reciprocally mounted in an enlarged recess 1 in said frame. A compression spring 4 is also positioned in said recess against the enlarged ortion 3 of the pilot member and is retaine in position against the same and in said recess by'means of a plug 5 secured in said arm in alinement with said spring and pilot member. Positioned'in alinement. with and above the pilot member 3 and reciprocally mounted in the other arm forming the upper, {outwardly positioned, bl furcated portion is a plunger 6, at the lower end of which is secured, preferably screwed, a combination punching and countersinking member 7. Said member 7 consists preferably ofa straight piercing portion 7 at its "lower end, a frusto-conical countersinking portion 7" adjacent thereto and an'annular stop flange 7. at the upper end of said frusto-conical portion. To the upper end of said plunger are pivotally connected links 8 by means ofa pin 10, said links being pivotally connected at their opposite ends bv means of another pin 10 with a lever 9. Said lever is pivotally mounted, near the end of the pivotal connection of the links 8, at the upper end of the upwardly extending supporting portion 1 of the frame 1 by means of a pin 11. Said lever 9 is pivotally connected at its free end, by means'of a link 13, with the operating lever 12 intermediate its ends, said lever being pivotally supported at its one end, by means of a pin 1%, in another upwardly extending supporting portion 1 at the upper end of the supporting frame 1.

In the outer end of the lower, outwardly extending arm 1 of the lower bifurcated portion of the supporting frame is secured a rivet set member 15 by means of threaded portion 15 at the lower end of said member. A sleeve 16 is reciprocally mounted on and around the member 15, the lower end thereof being provided with an enlarged, annular portion 16, which retains the same in a certain position relatively to theforming or upsetting portion 15 of the rivet set member, said forming portion consisting of a circular recess in the upper end of the member, The arm 1- ot the supporting frame 1 1s provided with an enlarged hole 1 surrounding the member 15 in which the enlarged portion 16 is adapted to reciprocate and in which is positioned a compression spring 17, the ends of which are positioned against said enlarged portion 16 and an enlarged, threaded portion 15 of the rivet set member, which threaded portion retains the member 15 in the arm 1 It will be noted that the upper end of the sleeve 16 is spaced upwardly from the upper end of the member 15 when the operating lever is in a raised position and exerts a constant force against the under side of the brake-band, thereby insuring constant force between the rivet and brakeband when riveting the lhier to the latter. Positioned in alinement with the members 15 and 16 is another plunger 18, at the lower end of which is secured a head member 19, which is adapted to engage the heads of the rivets for securing the brake liner to the band. At the upper end of the plunger 18 are pivotally connected the links 20 by means of a pin 21, which links are pivotally connected at their opposite ends to the operating lever 12 by means of another pin 21, substantially as shown 'in the drawings.

The metallic brake-band, indicated by B in the drawings, is positioned with its previously punched riret hole over the conical portion of the pilot member 8 with the brake liner A positioned within or against the face of the band B. The operating lever 12 is then shifted from the position shown by solid lines to the downward position, shown by dotted lines in Fig. 2 of the drawings, the combination punching and countersinking member at the lower end of the plunger 6 forcing the liner and band downwardly against the upper portion of the arm 1 and against the compression of the spring 4, piercing the brake liner A vith the piercing portion 7 a of the member 7 and countersinking the same with the countersinking portion 7 thereof. A soft metal rivet, such as copper, is positioned in the hole thus formed and the brake-band and liner with the rivet in position are then positioned on the upper end of the sleeve 16, as shown in Fig. 2 of the drawings. The operating lever 12 is then again shifted downwardly, the head member 19 at the end of the plunger 18 engaging the head of the rivet and forcing the same with the brakeband and liner downwardly :against the compression of the spring 17, permitting the small end of therivet to engage the forming portion 15 at the end of the rivet set member 15. upsetting the end of the rivet and forming a head thereon, substantially asshown in Fig. 4 of'the drawings.

It will be here noted that with my apparatus one person may punch and countersink the holes in the brake-band liner while at the same time another person may secure a brake-band liner to the band of another brake-band, thus econoniizing on time and energy.

invention the construction, combination and arrangement substantially as set forth in the appended claims.
